    Description

    FIELD OF THE INVENTION



    [0001] The present invention relates to a method and a device for treatment of human excrement by collecting and dehydrating the excrement as expelled from human body and more particularly to a method and a device for treatment of human excrement through collection and dehydration of primary excrement as expelled from human body without polluting the environment.

    BACKGROUND OF THE INVENTION



    [0002] In many areas where waterborne system is not available, people usually collect excrement in a container as it is expelled from the human body. The excrement is usually piled up with straw for undergoing anaerobic degradation. Such a heap sends forth a foul smell which pollutes the environment. US3921228A describes a decomposition toilet that includes a heating means. This document is considered as the closest prior art.

    [0003] There are also a number of previously known biological toilets to improve the above situation. However, these biological toilets are not satisfying in terms of dehydration efficiency and maintenance point of view because excrement stains the passageway causing unpleasant feeling to next user and excrement forms a high pile getting difficult to be dehydrated particularly in the center portion and new excrement hinders dehydration process. The present invention is a need for an improved method and a device to overcome the shortcomings of the prior art.

    OBJECTS OF THE INVENTION



    [0004] It is an aim of present invention to provide a method for treatment of human excrement by collecting and dehydrating the excrement expelled from human body.

    [0005] Another aim of present invention is to provide a device for treatment of human excrement by collecting and dehydrating the excrement expelled from human body.

    SUMMARY OF THE INVENTION



    [0006] To achieve the aforementioned aims, one aspect of the present invention provides a method for treatment of human excrement, according to the features of independent claim 1. Said method comprises, among others, the step of providing a chamber having a top opening through which excrement enters the chamber;
    The method also comprises the step of allowing the excrement to form a layer inside the chamber by setting up a storing porous plate crossing the whole length and whole width of an upper half of the interior of the chamber, wherein the upper part of said plate features to have a protrusion in the form of an equilateral-triangular base pyramid topped vertically under the centre of the outlet of the top opening and the lower side of equilateral-triangular base intersected perpendicularly to the central line of plate, and the plate further slopes downwardly and then horizontally away from top opening in the form of a series of corrugations whereby the excrement moves down the pyramid and the slope and then across the plate by gravity;
    The method further comprises the step of allowing liquid urine to fall down into the urine storing region of the chamber through perforations in the porous plate;
    The method also further comprises the step of setting up two solid excrement storing regions namely a front storing region located under the top opening and a rear storing region located away from the top opening, and the regions are separated by mounting a vertical baffle on top of said corrugated plate, whereby solid excrement is stored firstly at the front storing region and secondly at the rear storing region;
    The method still further comprises the step of dehydrating the solid excrement by ventilating the chamber interior by means of a ventilation system located at the top ceiling region of the front storing region which draws air in through the end wall of the rear storing region, down through the porous plate into the urine storing region and backup through the porous plate before exiting out through the ventilation system;
    The method can also comprise the step of providing an indirect heat source inside chamber wherein heat penetrates the solid excrement layers without touching.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT



    [0009] Fig.1 shows a perspective view of a bowl (1) to be used in the present invention. The bowl (1), provided for sitting on to defecate and urinate, includes an upwardly-tapered interior in a way that the top entrance inner circumference is smaller than the interior circumference of the said bowl (1) to avoid the excrement staining on the inner wall thereof. The bowl (1) further includes an inclined inner trough (2) extending inwardly and downwardly and a vertical inner trough (3) opposed to the inclined trough (2), with each of the troughs (2) and (3) having a curved surface forming a vertical passageway having an outlet (4) penetrating into the interior of the chamber (5) to minimize visibility. Each of the inner surfaces of the troughs (2), (3) is covered with a coating that improves the sliding of excrement. The inclined trough (2) has a bottom end centered vertically to the central point of the top entrance of the bowl (1) so that when human body sit on the bowl (1) at normal posture, the anus of the human body is at a vertical position above the central area of the outlet (4), as clearly shown in Fig.1, enabling solid excrement enters the chamber (5) directly through the passageway, whereas urine pushes the remaining solid excrement still left behind on the inclined trough (2) into the chamber (5).

    [0010] Alternatively, a squat pan (1a) of Fig.2 is used instead of the bowl (1) of Fig.1. As shown in Fig. 2, the squat pan (1a), provided for squatting across to defecate and urinate, includes an oblong interior. The squat pan (1a) further includes an inclined inner trough (2a) extending inwardly and downwardly and a vertical inner trough (3a) opposed to the inclined trough (2a) forming a vertical passageway having an outlet (4a) penetrating into the interior of the chamber (5) to minimize visibility. Each of the inner surfaces of the troughs (2a), (3a) is covered with a coating that improves the sliding of the excrement. The inclined trough (2a) here also has a bottom end centered vertically to the central point of the top entrance of the squat pan (1a) so that when human body squat across the squat pan (1a) at normal squatting posture, the anus of the human body is at a vertical position above the central area of the outlet (4a) enabling solid excrement enters the chamber (5) directly through the passageway, whereas urine pushes the remaining solid excrement still left behind on the inclined trough (2a) into the chamber (5) as clearly shown in Fig.2. Regardless of the difference between the bowl (1) and the squat pan (1a), their respective inner troughs (2,2a) and (3,3a) form an outlet (4,4a) providing a vertical passageway between them as the top opening of the chamber (5).

    [0011] Fig.3 shows a perspective view of a storing porous plate (6) to be used in the present invention. The upper part of the plate (6) features to have a protrusion in the form of an equilateral-triangular base pyramid (6a) wherein the lower side of the equilateral-triangular base of the pyramid (6a) intersects perpendicularly to the central line of the plate (6), and the plate (6) further slopes downwardly and then extends horizontally in the form of a series of corrugations (6b) wherein holes are distributed on the lower surface of the slope and on the surface of the corrugated area (6b) to allow urine falling down and to allow air penetration through the plate whereby a vertical baffle (6c) is fixed on top the corrugated area (6b).

    [0012] As shown in Fig.4, the chamber (5) having topped with a bowl (1) as per Fig.1 is defined by a first end wall located adjacent to the top opening, a second end wall located away from the top opening, and a pair of side walls (only one is shown) extending between the end walls. The storing porous plate (6) as shown in Fig. 3 is mounted across the whole length and whole width of the upper half of the interior of the chamber (5) wherein the top of the pyramid (6a) is located vertically under the center of the outlet (4) of the top opening and the lower side of the equilateral-triangular base intersects perpendicularly to the central line of the plate (6) whereby the pyramid (6a) provides three slopes to widen the movement of excrement down the main slope of the plate (6) and then across the horizontal corrugated plate (6b) by gravity. The vertical baffle (6c) divides the upper chamber interior into two separated storing regions namely a front storing region (13) and a rear storing region (14), wherein solid excrement is stored firstly at the front storing region (13) and secondly at the rear storing region (14). The urine falls into the urine storing region (15) through holes in the porous plate (6). A set of ventilation system comprising of a ventilating duct (8) topped with an exhaustion fan (9) and a wind turbine (10) locates at the top ceiling region of the front storing region (13) drawing air in through the end wall (11) of rear storing region (14), down through porous plate (6) into urine storing region (15) and backup through the porous plate (6) before exiting out through the ventilating system. An indirect heat source (7) locates at the rear storing region (14) to promote dehydration without touching. Excess liquid urine is drained out of urine storing region (15) through an overflow exit (12) located under plate (6) to avoid flooding of solid excrement layers. Eventually completely dried organic harmless substance is obtained through the manhole cover (16) at the rear storing region (14).

    [0013] Although embodiments together with structures and functions of present invention have been described in detail, many modifications and variations may be made from the teachings disclosed hereinabove. Therefore, it should be understood by those skilled in the art that any modification and variation equivalent to the scope of present invention should be regarded to fall within the scope of the appended claims.
